-- Application filed February 'T0 all whom it. may concern: j

Be it known that I, MICHAEL EARL Lorie, citizen of the United States, residing at Johnstown, in the county of l Cambria and State of Pennsylvania, have invented certain new and useful Improvementsfin Mine Cars, of which the following is a specification.

This invention sdirected to an improvement in steel mine cars, wherein the parts are made and adapted for assemblage in a manner to permit their convenient removal for replacement or repairs. l

The car proper is made up of a bottom piece, side plates and end plates, each relaconnection, one with another; there being included in the construction a center sill or beam, which extends the full length of the car and protrudes from both ends in order to provide for the connection of adjacent cars and also to absorb the shock to which such cars aresubjected. The center beam is made of a separate part, to facilitate its removal in the eventofdamage without necessitating the dismantling of the car structure.

The invention in its preferred form is illustrated in the accompanying drawings, in which 1- l j Fig. 1 is a plan view of the improved car.

Fig. 2 isa vertical sectional view of the same.

Fig. 3 is a transverse sectional view of the same.

Fig. l is a detail of the center beam.

Fig. 5 is a perspective view of the filler block.

The improved car comprises metallic, preferably steel bottom, sides 2, and ends 3. The bottom comprises a fiat plate, or corrugated as preferred, of a size corresponding to that of the car desired, the ends 4: of the bottom being upturned or flanged to receive the ends 3. The sides 2 are formed into the shape shown by pressing, either hot or cold, and hanged at 5 on both ends to receive the ends 3. rlfhe bottom edge of each side is flanged at 6, and the sides and bottom are united through thisside flange 6 being bolted or riveted to the bottom, the flanges 6 preferably resting on the upper surfacel of the bottom. Y i lThe ends 3, which are plain or corrugated as preferred, are secured in position by bolting or riveting said ends to the flanges t of' thebottom and the flanges 5 of the sides.

16, 1922. Serial No. 536,983.

The center beam, indicated generally at`vv 7, consists of a longitudinal angle or chanl nel member, extending full length of the car body and protruding beyond the ends thereof, as at 8 for a purpose hereinafter mentioned. This channel member is provided with angle-sections 9 in its mid-length, to support a ytwo-piece wooden sill 10, which extends from one end of the channel member to the center portion thereof. The channel member is preferably secured to the car bot tom 1,`by angle members 11, as shown. .If desired, the center beam may be constructed of Wooden sections or a section, and the angle members 11 extended full length of the bottom, and utilized to secure such wooden beam to the car bottom, as will be evident.

The extended ends of the center beam beyond the ends ofthe car proper, as at 8, are for the purpose of accommodating the draw-bar l2, and bumper 18. The drawbar l2 is bolted or riveted to the center beam, and has its outer end spaced from the beam proper, and lheld by a spacing block 14. The draw-bar at one end is provided with the usual stationary button-head pin 15 at one end, and a removable link pin 16 at the other. The bumper 13 is secured on the end of the center beam to resist jars, blowsand the like.

The upper edges of the sides 2 are provided with angle-form stifening strips 17, which extend throughout the full lengths of such edges.

In that type of center beam where the wooden center sill is omitted, there are provided fller Ablocks 18 of appropriate shape to fill the center beam, thus preventing coal leakage through and under the center eam.

It is apparent from the above description that the car, constructed as described, is made up of parts that are readily separable when necessary for repair or replacement, that the center beam is arranged to resist and take care of all strains to which such cars are usually subjected; and that the center beam construction materially assists in strengthening the load supporting function of the car.

It is of course to be understood that the car is provided with the usual axles 19, mounted in journal boxes 20, the usual wheels being also provided. The journal box-es are bolted directly to the bottom 1 of the car, as shown. An angle piece 21 is also gations 22. Obviously, the car ends may be rigidly secured as shown or hinged for swinging. The metallic bottom, sides, and

-end's may be cold-rolled or coldor hot-- pressed, and if bolts are used to fasten'the parts together, ordinary lool;l washers should be employed.

Having thus described the invention, what is claimed as new, is zy l. A mine oar having a bottom with upturned fianged ends and plain side edges, sides having bottom-edge flanges to rest upon and be secured to the bottom and being formed with end edge flanges, and ends having plain edges secured to theA end flanges p of the bottom and to the end edge flanges of the sides, and a center beam secured upon and `arranged wholly above the bottom and extending through and beyond the ends.

2. A mine car having a bottom with upturned flanged ends andy plain side edges, sides having bottom-edge flanges to rest upon and be secured to the bottom and being formed with end edge flanges, and ends having plain edges secured to the end flanges of the bottom and to the end edge flanges of the sides, a center beam secured upon and arranged wholly above the bottom and eX- tend'ing through and beyond-the ends, and

a filler for such center beam, said filler e,\;-

tending beyond the ends of the car.

3. A steel mine car having a removable center beam of hollow construction, and separate fillers of wood inserted in said beam, said fillers being spaced apart centrally of the car.

In testimony whereof, I affix my signature.
